Given I'm forced to pay for the BBC a fee for a service I don't use. I'd prefer they did it as cheaply as possible, maybe it will stop it getting even more expensive. The BBC's job isn't to create nice jobs.
There are many things wrong with the TV license system, but I think saying it is 'mandatory' is a little misleading. As the Wikipedia article states, you need a TV license if you want to watch or record live broadcasted material (and iplayer). You can own a TV and not pay for a TV license and use it for Netflix, YouTube, gaming etc legally.
For my entire adult life I've never paid for a TV license, and I have never broken the law and watched live content. Many in my generation have no interest in TV anymore.
It's worth appreciating that 'live broadcast' also includes media off the main networks, so if you watch a SpaceX livestream on YouTube (etc), technically you should have a TV License to do so.
That's not my understanding, unless that spacex livestream is by one of the TV networks.
"A licence is not required to view user generated content, clips and videos on YouTube. This includes live streamed content that is not part of a television broadcast. Or being broadcast at the same time by other means."
At least they most get high quality programs. Pitty the Germans with their expensive obligatory license, all to get a talking Brot 8 hours a night... - https://youtu.be/Rl_Rt0PNxn4
Like the wikipedia article says, modern digital signals and flat screens means correlating a set's emissions with a particular licensed broadcast is "difficult"!
I'd say impossible. For a van parked outside to determine you're watching BBC and not something else? Laughably impossible! Unless they peep through your windows?
You're not allowed to watch "something else" either - it's a national tax on televisions, not a BBC subscription charge.
Historically the detector vans tuned in to the local oscillator frequency generated by the television's "Heterodyne" tuning circuits. In order to tune to different channels, the TV generated different frequencies and used them to shift the broadcast an intermediate frequency to where they would decode it. If you know the intermediate frequency used by the TV (I believe they all use the same one), and can measure the local oscillator frequency, you know the channel being tuned to. You may well still know the frequency being tuned to with a digital TV, but each frequency now carries a multiplex of several TV or radio channels.
Your RF knowledge is no-doubt sound, the people saying TV detector vans are impossible have no idea what they're talking about.
But, ultimately the tax isn't on TVs. The tax is applied to people watching broadcast live television and it's used to fund the BBC, ITV, Channel4 and also used to pay OFCOM which regulates all other media.
If you search|scroll down the TV Licence article for "In 2013 it was revealed..." these days they can literally match flickering light seen through the window bouncing off the ceiling against currently broadcasting BBC | Channel 5, ITV, etc broadcasts.
Interesting privacy issue. Personally I'd want to protect my own home's "light emissions" from peeping toms. My home, my light!
It's remarkable anyone thinks it's okay for a licensing authority to adopt this Orwellian creepiness. The slippery slope is technology increasingly reveals more detail from incidental light and audio coming from private households. We should act now in policy-making to protect this information as we do or should do for biometric data.
Freeview receives data on the same 4 core broadcasts* that were used for analog, and in fact, freeview channels remain mux'ed in a way that BBC produced content is isolated to the 2 muxes that correspond to the old BBC1/BBC2 split.
So yes, it's still perfectly easy to find the Intermediate Frequency oscillator for a freeview receiver.
* During the analog/digital crossover period, the DTV signals were, obviously, at an offset from the associated analog UHF channel, since analog and DTV could not physically occupy the same frequency, but the fact remains that the DTV muxes were associated with one of the 4 existing channels (Ch 5 didn't have an associated DTV mux afaik)
edit:
here's a list of the mux allocations, you'll notice that all BBC programming is allocated to the BBCA and BBCB muxes, even though there's more than 4 overall muxes available these days.

What do you mean by "nice jobs"?
It’s not that hard to opt out. Don’t even recall what I had to do that’s how fast it was
I'll bite, who's forcing you to "pay for the BBC a fee for a service" you don't use?
GP likely lives in the UK where households are subject to a mandatory TV Licence, which fees are used to fund the BBC.

I do find that infuriating.

The hassle of "opting out" might be the force referred to:

This is very real. They also give you notice before their surveillance scan.
Surely this can't be real any more!
